PWM Lamp Dimmer using IC 555

This project discusses in detail about the PWM lamp dimmer. It will use IC NE555. Earlier the dimmers built on linear regulators was not efficient compared to the current one. For instance, if the old dimmers can achieve efficiency of 50% the new one is quite efficient to achieve 90%. Moreover, while the less power […]
